Professional diving watches such as Rolex Submariner are popular for their perfect time keeping ability in deep waters. In these Replica Rolex Reviews, we will share the reviews about the Rolex Submariner which will help to know about the perfect diving watch. The Rolex Submariner has the honor of first professional diving watch that was produced the Swiss master in 1953. The main designer of the watch Jacques Cousteau was a diving enthusiast and also served in the Navy before watch making. Being a professional diver, he was well aware about the necessities of a reliable diving watch. So the Rolex Submariner has following features:

Clear visibility in deep water with high contrast ratio black dial and big luminous hands.

Good water proof, antimagnetic and anti-collision structure.

Perfect corrosion resistance in different temperatures.

The first generation submariner with Ref. 6204 was slight different from 6202 and 6204 which was water resistant to 100m. The simple hand was changed with a “Mercedes-Benz” hand. During the same period, Rolex introduced 6205 models with a Submariner words on its dial. 6200 which was produced in 1954-1956 was the special edition of the Rolex Submariner. The difference between this model and other ones were the Roman numeral hour markers at 3, 6 and 9. The second generation came with the introduction of Ref. 6538 with same iconic “Mercedes-Benz” hand. The case diameter of 6538 model was increased to 38mm with Cal. 1030 Butterfly Rotor movement which had passed the COSC test and was the best movement at the time. “+” was changed into “BREVET” words below the “Crown” logo. The most notable aspect of the models was the water resistance to 200M.

Jean Piccard and Auguste made a new submarine diving record when they dived to 3150 meters in 1953. At the same time, Rolex Submariner was born and was used in a diving adventure in 600 meters. Casino Royale was broadcasted on 21 October 1954 which was the first time when 007 appeared on the screen. The main character Barry Nelson wore the Rolex Submariner which was released a year ago. Sean Connery also wore the watch in Dr.No but Rolex didn’t want to sponsor him. So the director had to lend its own NATO strap Submariner to the actor. It is due to this fact that people nowadays change the original Oyster bracelet of Submariner into a NATO cloth strap.

Ref 5508 (1958-1965) was the third generation Submariner with a Cal. 1530, 37mm diameter case and was water resistant to 100 meters. But the price was higher from the previous models and also had a red version “Submariner” words on the dial. The radioactivity increased due to the change of luminescent material. The 5510 was produced for only two years and was water resistant to 200 meters.

Rolex Submariner reached to its fourth generation with ref. 5512. The new models had various differences from the previous versions.

The bezel’s material was changed into solid steel from mixed rubber.

The bezel’s flutings were widened and were much bigger than previous models.

The crown of the Submariner was smashed in an accident in late 50’s, so guards on the both sides of the crown were added which is still in use.

A waterproof apron was added on the tube.

Beneath the “Crown” logo, there were three round points which were used as sports model sign.

Bracelet was prominently improved.

The case diameter was improved into a genuine sports watch size 39.5mm. The Cal. 1750 was used in 5512 which was the most advanced product of Rolex at that time. Due to its durability and accuracy, it has still a good reputation.

Ref. 5513 was a bit cheap version of 5512 with quite long lifeline and also with large production. The previous luminous markers were free from frames but later on they were equipped with frames but not metal ones. 1530 movement was used in 5513 model which was then switched to 1520 movement after few years. 5513’s military version was ref. 5517 that featured canvas military strap with much stronger sword hands but the price was very expensive. IOS (International Organization for Standardization made detailed requirements on the specifications of diving watch during the production of 5513. Here are the details which were published on July 1, 1981.

The watch must be readable in the dark from 25cm distance with proper time identification with time span on the bezel.

The timepiece must be DC anti-magnetic for more than 60 Gauss.

Even if it falls from 1 meter height on a hard word, it must not get any damage.

Plus 20kg resistance to external force.

The watch must work properly after immersing it in 3% salt water for at-least 24 hours.

The watch must have the ability to withstand 40 C -5 C -40 C temperature cycle.

A diving watch must have above requirements but watch such as Submariner is a professional and rare diving watch.

Ref. 1680 was one of the earliest models of Submariner with date function. Cal. 1570 movement was used in 1680 with water resistance to 200M and the production lasted from 1965 to 1980. Famous “Red Sub” was another model of 1680 that was loved worldwide by watch fans. Ref 16800 featured a sapphire crystal and was water resistant to 300 meters. The watch was equipped with 3035 movement and was also more stable and accurate than other models. In 1989, 168000 was produced but soon it was replaced with 16610 immediately.

Submariner was produced for the exploration of underwater world with special features. In-fact Submariner was not as spectacular as Daytona and also not had many functions but it was a gift for adventurers with powerful practical valve. 5513 was discontinued in 1989 and modern Submariner with ref 14060 emerged. Sapphire crystal was used to prevent the scratches and other damages that were caused in sports. But the hard brittle characteristic was not good enough to prevent collision. The new Rolex no date mechanism with Cal. 3030 was produced in 2001 that replaced 3000 and the previous model 14060 was renamed to 14060M. The newest Submariner Date with 300 meters waterproof was ref. 16610. 3135 new movement was used along with sapphire crystal. Rolex introduced 16610LV with green bezel as special anniversary edition on the 50th anniversary of Rolex in 2003. Rolex Submariner has been successfully retaining the top spot in the diving watches for over sixty years.
